See I can handle remakes, dariofulci speculated that "pretty soon we will have a remake to sit next to
every original in our collections."
I think that actually would be cool.
What it comes down to is the quality of the remakes though. With April Fool's Day you especially have a challenge as if you change the ending to be more in line with what people expect from a slasher it could become just another routine slasher film, but if you leave the same twist in as the original it would annoy fans of the original.
My advice would be do a twist ending, but make it different enough from the twist in the original that new and old fans dig it.
I feel bad for anyone reading the comments who hasn't seen the original as they're spoilers, but, ah well, I knew what the ending was generally about and still dug the movie.
This was one the movies focused on in the excellent slasher film documentary "Going to Pieces: The Rise and Fall of the Slasher Film". So if they continue remaking slasher films which were mentioned in said documentary that have endings that some people don't dig, next we should be expecting a remake of "Happy Birthday to Me" and then "Friday the 13th 5: A New Beginning." That remake will have Wrong Turn inbred killers instead of the stereotyped backwoods ma and son duo, The Macarena instead of the robot dance, and the new Tommy Jarvis will not have made scary masks but instead be good at CGI. It'll be jiggy!
